Useful first.

Siemens

S7-1500 watchdog after a TIA download

CPU comes up, then STOP. Don’t raise the watchdog first — find the extra 10 ms tag group on the HMI.

Allen-Bradley

Kinetix 5700 following error after a power hit

Trend actual vs command. After a weekend outage the drive often loses the motor nameplate.

Robots

Weld touchups creeping back on shift 3

Heat soak on the fixture, not the path. Pull TCP offset and gun water temp before you touch the pendant.

Networks

POINT I/O rack dropping every 47 minutes

IGMP snooping on, still drops. Capture the scanner, not the HMI. Duplicate IP is rarely the actual fault.

Industry 5.0

No more robot touchups

Adaptive machine-based learning. KUKA + TIA was the prototype. Expanding to FANUC, ABB, and Logix.

Work

What belongs in an RFQ

Platform, cell ID, symptom, what you already tried, and when the outage is. PDF or photo is enough.
